From the AX8 datasheet it is possible to confirm that its Operating Temperature Range is from 0°C to +50°C (+32°F to +122°F). However one should not relate this information with the Internal Temperature Sensor displayed in the camera webserver, which has different limits.

One should make sure the camera is installed in an environment where the ambient temperature does not reach 50°C (122°F). The camera was designed for this type of environment and certainly its internal temperature will be higher than the ambient temperature.

The Internal Temperature limits of the camera are not disclosed by FLIR.

FLIR also recommends the use of the cooling bracket to help dissipate the camera internal heat.
